Scientists have been growing tracheas and tissues and organs for years.
But now, they have successfully transplanted laboratory-grown vaginas into
young adults who were born without one. The girls all had Mayer-Rokitansky-Küster-Hauser
Syndrome, a rare disease that affects the female respiratory system by
deforming organs or causing them not to form entirely.

According
to CNN, the scientists started the challenging process by building a scaffold
that mirrored the dimensions of the patients’ missing organs. They then
extracted cells from their muscles and tissues, which were then strewn across
the scaffold and nurtured so that it grew outside of the body. The most
important part of this innovation is that because the new organ is grown
entirely from the patients’ cells, the patients’ bodies are much less likely to
reject the organ.

So far, so good. The vaginas seem to be accepted in their new bodies
and are functioning properly, giving the patients normal lives, finally.
